I'm an ex-pc/windows user. I was a PC user since I was a kid. As a graphic design major I became familiar with macs in college, but only recently got so absolutely fed up with Windows that I nearly pitched my old laptop out the window and finally bought my new macbook pro which I LOVE LOVE LOVE!! Anyway, besides graphic design, I am also a realtor, and this is where my Windows issue comes into play. Unfortunately the MLS (the online database realtors use to access properties on the market) is ONLY accessible via Internet Explorer on a Windows platform. Now I wish that I could totally be free of the Windows world, but unfortunately, because of this ONE issue, I can't. I was thinking of installing Parallels and using it for the SOLE PURPOSE of accessing the MLS. If I do this, am I opening myself up to malware problems? I understand the ins and outs of what keeps OS X so secure, but am confused as to how that is all incorporated once you throw Windows back into the mix. Any advice?
